PLOW.

been reached to make furrows in the reverse direction without having-to turn the plow.

The improved plow consists essentially of two frames arranged one upon the other, which are. each provided with supporting wheels and sharesand work in turn according to whether the plow is runningin one direction or in the opposite direction. When the machine has reached one end of J the field to be tilled, and if it is desired to come back in the reverse direction, the upper frame is swung through an angleof 180 with respect to the lower frame, about laterally arranged hinges and isthereby brought to aworking position on the part of the ground which has'notyet been plowed and the lower frame, which has just finished its working travel is then folded down over the other. frame which is about -to begin to work, by a swinging movement of180 about the samehinges.

' The two frames are in fact connected together. along each of their longitudinal edges 7 frame has its support atthe bottom of" the p to the border line m '(Fig. 7-) of the-field to be tilled, andrif it is desired to begin a frames may be made ad by a system'of joints. or hinges forminga pivotal and'detachableconnection. When the end of-vthe field isreached', one of the two systems is freed. was to permit the upper frame to pivot or swing with respect to the other about the hinges located at the other side. a

The hinges or articulations must be so arranged that the frame which is about' to i work maybe on 'ahigher level than the frame which has just finishedits working stroke, prior to 'the' folding down of the latter over the first frame, since the frame which is to begin to work rests on the untilled part ofythe groundqwhile, the other furrows." The difference in the levels-of both just-able according to the depth of the furrows. i v

' The plow may be drawn by two windlasses carried on locom'obiles which'move at both ends ofthe field, in'directions at right angles with-.thefurrows,

.As shown in the drawing, the improved plow mayflbe,considered as formed of two superimposed plows which work in turn, one inthe direction of the arrow fand the other ground for working in the in the direction shown by the arrow; P, I Each of the plows comprises-a frame,,a ora provided with shares, 11 or b andv carried on afrontsteering or guiding wheel 0 or 0 which i runs in the nearest: of; the I furrows made in the last working strokegafront ground wheel 6 orc .which runs upon the,

untilled soil and consequently lies on a higher level than the furrow wheel 1, c and two rear supporting .wheels d or d which respectively follow those of the furrows which havejust beenmade which are .located at both sides. V e r In-the position of parts shown in full lines, the. shares 6 alone are at work, the plowis drawn in the direction of-the arrow 7 f by means of a cable 2' connected to the front draw bar j. of the plow and wound on a Windlass 70 carried on alocomobile Z, which latter can move in a direction at right angles to the direction of the, furrows and be broughtto such 'a positionthat the traction always-takes place along the longitudinal central line of the plow.

When theplow has approXimatelycome comes to the position shown in -broken lines in Figs. 1 and 2. The hinges n occupy such a position that the frame a when folded down upon an untilled part of the ground,

may stand on a higher lever than that of the 7 to come over the frame a The plow is then drawn along the field in the direction shown by the arrow f by the Windlass 70 provided on the locomobile Z the cable i being then connected to the draw bar j which at that time extends in the central longitudinal plane of the machine. The horizontal transversal distance 9 (Figs. 1 and 2) between the hinge axis and the line ,of travel of the nearest plow share 6 or b is equal to half the distance 1 between two adjacent furrows so that the right hand furrow dug out in the direction 7 will be at the,normal distance 1" from the right hand furrow made in the previous stroke.

When the plow has thus been laterally turned upside down as described, the hinges a are on the left side of the machine,(Fig.

2) andto make a' further strokeinthe direction of arrow the plow frames will have to be tilted .over about said hinges. Of course it will then be necessary to effect this, to disconnect both frames from. each other at the hinges n in the same manner as it had been necessary to disconnect the same from each other at the hinges n in order to effect the tilting operation above, described. To permit of thusrdisconnecting the frames from each other alternatively at one side and. the other, the hinges n, n will be provided with movable pivots or studs and means may be provided whereby said studs will engage automatically into the corresponding holes or bearings when one frame is swung down upon the other all, of the studs or pivots being engaged in the corresponding bearings at both sides of'the machine when the latter is in operation so that both frames are securely held together.

The draw bars j, j may be dispensed with. When they are provided, they preferably have a length equal to the width of the plow. While the machine is working in the direction of arrow f and trailed through the I draw bar 9', the draw bar 3' may be swung laterally as shown in Figs. 1 and 7 so that the cable i 'may beimmediately in a proper position for efiecting the traction in the next stroke,the locomobile Z being meanwhile advanced transversely by a suitable distance. The same will of course be done for the draw bar when the machine is running in the direction 7. The front furrow Wheel 0 is so mounted as to be vertically adjustable whereby it may be raised to a higher position when plowing is started, said wheel running then on an untilled ground.

The front ground wheel 6 is mounted in a yoke which may swing around a vertical axis so that the wheel may easily run out of eventual wheel tracks and have no influence on the steering of the plow.

The plow shares may be provided in any convenient number and the construction shown and described may be varied in many respects withoutdeparting from the spirit of the invention and the scope of the appended claims.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A plow comprising in combination two normally superimposed frames, plow shares to pivotally and detachably connect both frames to each other, along two lateralopposite edges of the same. V,

2. A plow comprising in combination two normally superimposed frames, plow shares and supporting wheels on each of said frames, the shares and wheels on one frame being adapted for use when the plow is run- 'ning in one direction and the'shares and wheels on the other frame being adapted for use when the plow is running in the opposite direction and connecting means adapted to pivotally and detachably connect both frames to each other along two lateral opposite edges of the same,'the articulation axis of the hinges at each side of the-frames being transversally and horizontally ata distance from the line of travel of the nearest plow share equal to half the cross horizontal distance between two adjacent shares on the same frame.

3. A plow comprising in combination two normally superimposed frames, plow shares and supporting wheels on "each of said frames, the shares and wheels on one frame 7 being adaptedfor use when the plow is running in one direction and the shares and wheels on the other frame being adapted for use, when the plow is running in the opp o site direction and connecting means adapted to pivotally and detachably connect both frames to each other along two lateral opposite edges of the same, thearti lation axis of the connecting means at one side of the frames belng above, and at the other .side, below the level of the frames.
